A transactional email is an automated email sent from one sender to one recipient, usually related to account activity or a commercial transaction. Unlike traditional bulk marketing emails, transactional emails contain information that is uniquely relevant to an individual recipient. Common uses for transactional email or types of transactional emails include:

• Account alerts (account creation emails, subscription ending, credit card expiring, etc.)
• Abandoned cart notifications
• Event notifications (shipping notifications)
• Order confirmations and purchase receipts
• Responses to customer service inquiries
• Password reminders or resets
• Requests for feedback
• Subscription welcome emails

Transactional emails are triggered by a users specific action and contain only critical, relevant information to the receiver. They are typically sent to individuals one at a time and contain data or content that is specific to that user. Transactional emails facilitate a commercial transaction or relationship or provide an individual customer with the information necessary for a transaction or relationship. They allow you to provide information that is uniquely relevant to the recipient and can provide requested information or let them know about order status changes.
